• Popular choice for copper brazing air conditioning and refrigeration connections
• Flows into tight connections when heated above its liquidus temperature
• Wide melting range allows operators to fill loose connections and "cap" or "build-up" around the finished joint
• Popular brazing filler metal for HVAC and refrigeration connections
• Recommended joint clearance of 0.003 in to 0.006 in
• For brazing brass or copper-to-brass Stay-Silv® white flux is suitable for most applications
• Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including Stay-Silv® 15, should not be used if the braze is exposed to sulfur or sulfur compounds in service
• Not recommended for brazing steel or other ferrous metals due to sufficient lack of joint ductility
• Suitable for brazing low nickel (10% maximum) copper/nickel base metals

Stay-Silv® 15 phos-copper filler metal is the industry standard for air conditioning/refrigeration applications. It's melting range is useful in filling wider clearances while providing good service ductility. Complies with the EU Reach and RoHS directive.
